  * SECURITY UPDATE: Check that repository is trusted before downloading
    files from it (LP: #1858973)

    (Closes: #944696) (#LP: #1858972)
    - apt/package.py: Use all hashes when fetching packages, and
      check that we have trusted hashes when downloading
    - CVE-2019-15795

    can be passed to the functions. It defaults to the value of the
    APT::Get::AllowUnauthenticated option.
    - Bump Breaks aptdaemon (<< 1.1.1+bzr982-0ubuntu21.2), as it will have
      to set that parameter after having done validation.

    - Adjustments to test suite and CI to fix CI regressions
    - Automatic mirror list update
